Continuous cooling transformation of under-cooled aus- tenite for Nb-V microalloyed spring steel 60Si2CrVATHua-lin Wu, Fu-ming Wang, Chang-rong Li, Qing Yan, and Bo ZhangAbstract： The continuous cooling transformation curves of under-cooled austenite in Nb-V microalloyed spring steel 60Si2CrVAT were measured by using a DIL805A quench- ing deformation dilatometer. The microstructure changes of under-cooled austenite in the tested steels at different cool- ing rates were studied by the metallographic method cou- pling with the microhardness method. The effect of Nb con- tent on continuous cooling transformation of the tested steels was analyzed. The experimental results show that with the increase in Nb content, the high-temperature and medium-temperature phase transitions were promoted,

Nonlinear calculation of Hardgrove grindability index for mixed coal used in pulverized coal injectionJian Duan, Long-zhe Jin, Sheng-nan Ou, Zhao-zhong Ding, and Fei GuoAbstract： Both experiments and theory analysis proved that the Hardgrove grindability index （HGI） of mixed coal was nonlinear with its mixture ratio, which was explained by the theory of micro-grinding-ball effect. The HGI of 5 mixed coal samples was measured in lab. Because the HGI data of different mixed coal samples change in different ranges, they could not be directly compared with each other. Though normalizing by the relative grindability ratio （RGR）,

The low-temperature selective catalytic reduction （SCR） denitrification of a flue gas was carried out with Ce-MnOx/ACFN. The denitrification efficiencies were studied by modifying the activated carbon fibers （ACF） and changing the Ce-MnOx loading capacity, Ce/Mn molar ratio and operating conditions respectively. Ce-MnOx/ACFN as a SCR denitrification catalyst has good activity at 70-110℃. The denitrification efficiency increases with rising temperature, and it improves obviously after the ACF is modified by nitric acid. With the increasing of Ce-MnOx loading capacity and Ce/Mn molar ratio, the denitrification efficiency increases firstly and then decreases; but with the increasing of NH3/NO molar ratio in the inlet flue gas, it increases firstly and then tends to be stable. When the volume fraction of vapor in the inlet flue gas is above 8% the denitrification efficiency decreases with the vapor volume fraction increasing.

Optimization algorithm based on Lab VIEW parallel operation and its application in Ni-Ti alloy wire dieless drawing Hong-gang Zhang, Yan-bin Jiang, Zhi-hao Zhang, and Jian-xin Xie Abstract： An optimization method based on LabVIEW parallel operation was proposed to improve the com- puting speed of the traditional genetic algorithm. When applied in a multi-core computer, the optimiza- tion method can achieve multithreading concurrent operations, thereby improving the efficiency of com- putation obviously. The initial speed-path of Ni-Ti al- loy wire dieless drawing was optimized in an eight-core computer by using the optimization method. Com- pared with a method based on MATLAB program, the operation time of the optimization method is only about 1/8 as long as that of the former. Experimental results show that after adopting the optimized speed-path, the length of diameter fluctuation is about 24 mm, which is far less than that of other speed-paths such as the S-line style or linear path.

Moreover, the qualities of manuscripts and editing are improving, and its influence and international status reaches a high level. Under ＂the International Influence of Chinese Science and Technology Journals Promotion Plan＂, the development and internationalization of JCPS will be further promoted.

基于Web of Science数据库的技术经济学科国外重点核心期刊分析

新形势下,技术经济领域的研究对于推动实现我国“十四五”规划和二○三五年远景目标起着至关重要的作用。但是技术经济研究在国外的核心期刊中分布较为分散,研究文献获取不够聚焦,本文利用Web of Science数据库,筛选以技术经济为主题的研究文章,并根据文章所发表的期刊进行了数据统计和分析,对技术经济领域国外重点核心期刊进行了提取,定位了总被引次数前1 000次的国外核心期刊、高被引论文中排名前十位的国外核心期刊、以及发表篇数排名前十位的国外核心期刊,并对高被引和发表篇数均为前十名的国外核心期刊进行了介绍,研究结果可以在一定程度上为技术经济领域研究者提供国外研究文献获取和研究成果发表方面的参考。

中文核心期刊创新驱动发展优化路径——以《中文核心期刊要目总览》为例

21世纪的今天,科技创新的重要性在现代社会变得越来越显著,科技创新有助于改善传媒、教育、通讯、交通等科技环境,推动社会全面发展。基于传媒环境创新驱动发展的形势,中文核心期刊评价工作因科技创新发展需要应运而生;中文核心期刊评价不仅是文献计量学研究的实际应用和组成部分,同亦是人文社会科学研究内容之一,更是媒介科技创新发展的必要环节;可促进学术交流和国际合作,推动科研水平提升,防范学术不端行为;对于学术研究和科研社群的发展、优化期刊使用、合理分配学术资源、提升期刊传媒竞争力、促进中文期刊国际化、激励科研人员学术研究积极性等有着不可估量的影响。

论中文高质量科技期刊出版开放获取的发展转型:现状、成因及建议——从青铜OA迈向金色OA

开放存取(Open Access, OA)是不同于传统学术传播的一种全新机制,其核心特征是在尊重作者权益的前提下,利用互联网为用户免费提供学术信息和学术研究成果全文服务,科研人员不需要通过付费就能访问学术资源及学术论文的全文。与科技期刊OA出版的国际发展大势相比,国内学术出版界的OA出版相对滞后,特别是中文科技期刊的OA出版模式亟需从青铜OA向金色OA转型,以加快与国际学术出版的接轨,进一步提升中国科技期刊的学术影响力。本文以入选《中文核心期刊要目总览(2023年版)》的部分高质量科技期刊为研究对象,通过对样本期刊官方网站和部分国内外开放获取学术平台的调研发现,在选取的148个中文高质量科技期刊研究样本中,青铜OA期刊占绝大多数,金色OA期刊占比很小,这与国际发展大趋势不相符合,不利于我国OA期刊的规范化和持续化发展。造成中文高质量科技期刊OA发展滞后的成因主要有期刊出版单位和作者OA主动意识薄弱、期刊OA规范性明显欠缺、国内OA学术平台建设相对落后等。在此基础上,提出了实现我国中文高质量科技期刊从青铜OA向金色OA出版转型的六大建议,即:(1)加强国家政策引导;(2)规范版权和知识共享协议;(3)制定合理的APC收费标准;(4)积极加入国外OA期刊数据库;(5)强化国内OA学术期刊平台建设;(6)普及开放获取和开放科学知识。

基于CSCD、Web of Science数据库的2015年新疆医科大学发文分析

目的通过对2015年新疆医科大学科研人员在Web of Science核心合集来源期刊和中国科学引文数据库(CSCD)来源期刊的发文情况进行分析,深入了解我校科研方向、科研实力和科技影响力。方法利用CSCD和Web of science核心合集数据和JCR数据库分析新疆医科大学在2015年的总发文量、影响因子、学科类别及JCR分区、高影响因子期刊分布情况等。结果发现新疆医科大学科研人员在CSCD和Web of Science核心合集期刊论文发文量不平衡,大量论文集中在影响因子偏低的期刊杂志上,而影响因子较高的期刊上发文均偏低。结论我校作者发表在中外文核心期刊上的论文学术水平参差不齐,呈现单一趋势,科研人员应努力提高自身学术水平;同时,学校应采取相应机制,鼓励师生多撰写高水平的文章,发表在高质量的期刊上。
